Food webs are affected by the space around them, but ecological models struggle to capture the coupling of spatial and trophic processes. Trophic metacommunity theory proposes to unite traditional metacommunity theory and food web theory.
To illustrate the potential processes underlying trophic metacommunity theory, we will look at empirical patterns in the aquatic invertebrate food webs in tropical bromeliads. Using observations, experiments and simulations, I will show that these patterns depend on the interactions between key trophic metacommunity processes: stochasticity, niche differences, spatial movement, predator functional responses, and spatial information processing.
